I mean music has always had those years when there was a down period of talent or good music. We forget that we are the first people to have access to all the music from previous generations in the palm of our hands and it kind of sweeps under the rug how artists back in the day flopped or an artist's career was considered over until two or three albums later when they drop one of their best.
We kind of put our perspectives into a vacuum only remembering the best of the best music of the last 50 years as if it was constantly happening and now of a sudden, it stopped because of the gen z.
We grew up in ringtone rap era breh where dudes wore XXXXL t-shirts. We grew up on songs like Laffy Taffy lol. How is that better than most the microwave music out today?
For the most part other than dudes like Lil Wayne, Jay Z, Kanye, etc. The Mid 2000s were filled with trash ass one-hit wonders and songs we refuse to listen to ever again we just glorifity the best parts.
IMO, Rap didn't resurge until the blog era with the birth of K dot, Drake, Cole, Cudi, Asap Rocky, Mac Miller, Big Krit etc.
It happens. Right now we are back in a down period. And eventually, we will be back.
